RESILIENT TIRE.

Specification of Letters Patent.

Patented Sept. 2, 1.913.

Application filed August 28, 1912. Serial No. 717,468.

/'o all 'who/7L 'it' may concern Be it known that l, FRANK, Rune, acitizen of the United States, residing at Omaha, in the county ofDouglas and State of Nebraska, have invented certain new and usefulImprovements in Resilient Tires, of which the following .is aspecification.

This invention relates to improvements in resilient tires, and has forits object to pro vide a tire of this class which may be convenientlymanufactured, will be durable in wear, and to be so constructed that acomparatively high degree of resiliency may be provided upon theperiphery of a wheel within a limited space.

The invention consists of the novel con struction, combination andarrangement of parts as described herein and claimed and as illustratedin the drawing, wherein,-

Figure 1 is a side view showing a part of the resilient tir-e, a portionbeing in longitudinal section. Fig. 2 is a transverse section on line 22 of Fig. l. Fig. 3 is a plan view showing a part of the tire. Fig. 1l.-.is a detail illustrating, in longitudinal section. a. modified form ofa layer.

Referring new to the drawing for a more particular description, numeral5 indicates a tire consisting of a body portion 6 substantiallyrectangular' in crosssection and a base 7 formed, in cross-section, withconvexed end-portions 8.

The herein described tire is particularly useful in connection withhorseless vehicles, and is employed as a substitute for the com binedouter and inner tires in general use; and it will be understood that thebase 7 may be supported upon the rim (not shown) of a vehicle wheel.

The principal part of the tire is preferably constructed of rubber. Inorder that it may have greater elasticity,numerous perforations orapertures are formed transversely in body-portion G, these being ar-'anged in the series indicated respectively at 9, l0, 11, and 12, eachof the apertures of a series being disposed at the same distance fromthe base 7 and the arrangement is such that each of the apertures ofeach series will be disposed in alinement with an aperture of analternate series, radially of the wheel, and on this account when thewheel passes over an obstruction, a high degree of elasticity isprovided, the yielding of the rubber, of course, depending upon the sizeof the alining apertures.

In order that a resistance may be provided for stresses which aredirected radially, as when the wheel moves over an obstruction, anelastic arch is disposed over each of the transverse apertures, andthese arches are best provided by the corrugated layers 13. Layers 13are corrugated or curved longitudinally, and it will be seen byreference to Figs. l and 2 that they form an arcuate wall above andparallel with each aperture. lhey are formed of flexible resilientmaterial, as the attenuated strip 111, which may be of sheet metaldisposed between fabric sheets 15 and 1G.

rlhe tire, as described, may be eonveniently manufactured. By use ofadhesive material the fabric sheets and the metallic part of a layer areheld together, and the fabric adheres to the rubber at the time the tireis formed. The endless layers thus provided are flexible and elastic andthey reinforce the tire in such a manner that the tire, while havingcomparatively a limited thickness and width, has a high degree ofelasticity, and by its use the pneumatic tire may be dispensed with.

The layers have a less width than the tire, and therefore they may bewholly surrounded by or embedded in the rubber. At 17 and 18 areindicated elastic reinforcing members. 'lhey may be constructed of thesame material as layers 13, and are of serpentine, endless form. Member17 is disposed outwardly of the convexed ends 8 of the base, and member1G is disposed within the base 7. They operate to sustain the stresseswhen the tire encounters obstructions, and tend to prevent spreadingl ofthe base and the rim in which the base is gene lally disposed.

lVhile I have explained in detail the construction of layers 13, 17 and18 I do not limit myself to exactness, and the number of metallic sheetsin each layer may be greater or less as may be desired.

At 19 (Fig. ll) is indicated an elastic reinforcing member consisting ofelastic metallic sheets L a, disposed in alternation between fabric orrubber sheets 0,' and layer 19 may be substituted for layers 13, 17 and18, if desired. These layers are useful in the construction of the tiresused upon the wheels of trucks, or other wheels of heavy construction.

At 20 is indicated a longitudinal ridge formed upon and at the middle ofthe periphery of the tire, transverse ridges 2l also being formed uponand at longitudinal intervals of said periphery to form therebetween thedepressed panels 22, these parts, when the tire is in use, tending to.prevent skidding.

Having fully explained the several parts and their uses a furtherdescription relating to operation is not necessary.

What l claim and desire to secure by ters Patent is,-

l. A vehicle tire comprising an elastic body portion formed with aplurality of rows of transverse openings, the openings of a row beingarranged in staggered relation to the openings of an adjacent row, and aplurality of elastic metallic members of serpentine formation extendinglongitudinally of the body portion and embedded therein, the outwardlybowed portions of one serpentine member being opposed to the inwardlybowed portions of the adjacent 2. A vehicle tire comprising an elasticbody portion formed with a plurality of vrows of transverse openings theopenings of a row being arranged in staggered relation to the openingsof an adjacent row, and a plurality of elasticmetallic members ofserpentine formation extending longitudinally of the body portion andembedded therein, the outwardly bowed portions of one serpentine memberbeing opposed to the inwardly bowed portions of the adjacent serpentinemember, said openings being located between the opposed concave portionsof said serpentine members, the outer of said metallic members being ofmore pronounced serpentine form than the inner,

ln testimony whereofv I have aIiXed my signature in presence of twowitnesses.
